SIMPLIFIED ENVELOPE

PROBLEM TO BE SOLVED: To provide a simplified envelope whose adhesive layer does not adhere to other things before sealing and generates no waste material such as releasing paper at the time of sealing. SOLUTION: The simplified envelope comprises an envelope front cover piece 2 having a strip top 2a with release layers 14a, 14b formed on a top, a sealing strip piece 5 with adhesive layers 20a, 20b formed on it which adhere temporarily to the release layers 14a, 14b, a lower backing paper piece 4 which extends downward from the sealing strip piece 5 via a folded line 16 for unsealing and joins with the lower side and both sides of the primary surface 2b of the envelope front cover piece 2, and a upper backing paper piece 3 which extends upward from the envelope front cover piece 2 via a folded line 10. The sealing of the simplified envelope can be achieved by folding the sealing strip piece 5 and the upper backing paper piece 3 in the direction of backward in series, and then bonding them. Also, the simplified envelope is free from the adhesion of other things to it because the adhesive layers 20a, 20b are protected by the release layers 14a, 14 before use, and needs no releasing paper which causes a waste material at the time of sealing it.
